摘要：[目的]以2种黑杨派无性系为研究对象,观察杨小舟蛾产卵后产卵植株和邻近植株对幼虫生长的影响并测定各处理叶片营养物质和次生代谢物质的含量变化,探讨2种黑杨派无性系在杨小舟蛾产卵后是否产生诱导抗性。[方法]杨小舟蛾在欧美杨108号(108杨)和欧美杨111号(111杨)产卵后,观察幼虫取食产卵植株、邻近植株和对照植株叶片的存活状况,再分别测定3种处理叶片的可溶性糖、全N、游离氨基酸、单宁和总酚5个指标的含量变化,研究2种黑杨派无性系诱导抗性的产生情况。[结果]取食2种黑杨派无性系3种处理叶片的幼虫存活率均差异不显著。108杨的产卵植株和邻近植株的可溶性总糖含量均显著低于对照;111杨的产卵植株和邻近植株的二糖和全N含量均显著低于对照植株,且产卵植株的游离氨基酸含量显著低于对照,同时,108杨邻近植株的游离氨基酸总量显著高于产卵植株和对照; 111杨的产卵和邻近植株的总糖/全N值都显著高于对照。108杨产卵植株的单宁和总酚含量都显著高于对照,而邻近植株的二者含量与对照差异不显著。111杨产卵植株的单宁和总酚含量都显著高于对照;同时邻近植株的单宁含量显著高于对照,而总酚含量与对照差异不显著。[结论]杨小舟蛾产卵使2种黑杨派无性系的产卵植株和邻近植株的营养物质含量都发生改变并且次生代谢物质含量不同程度增加。所以,2种黑杨派无性系的产卵和邻近植株都产生了一定的诱导抗虫性。
[Objective] To study the induced resistance of two clones of Populus section Aigeiros after oviposition of Micromelalopha sieversi(Staudinger) through observing the effects of the oviposited and neighboring plants on the growth of the larvae and measuring the contents of nutrients and secondary metabolites.[Method] The survival of larvae feeding on the oviposited, neighboring and controlled leaves of Populus × euramericana ‘Guariento' and P.×euramericana ‘Bellotto'was observed, then the contents of soluble sugar, total nitrogen, free amino acid, tannin and total phenol in the leaves of three treatments were measured to study the induced resistance of the two clones after oviposition of M.sieversi.[Result] There was no significant difference inthe survival rate of larval among the three treatments.The content of total soluble sugar in the oviposited and neighboring plants of P.× euramericana.‘Guariento' was significantly lower than that of the control plants. The content of disaccharide and total nitrogen in the oviposited and neighboring plants of P.×euramericana.‘Bellotto' was significantly lower than that of the control plants, and the content of free amino acids in the oviposited plants was significantly lower than that of the control plants.At the same time, the total amount of free amino acids in the neighboring plants of P.× euramericana.‘Guariento' was significantly higher than that of the oviposited and the control plants. The ratio of total sugar to total nitrogen in the oviposited and neighboring plants of P.×euramericana.‘Bellotto' were significantly higher than those of the control plants. The contents of tannin and total phenol in the oviposited plants of P.× euramericana.‘Guariento' were significantly higher than that of the control plants, while there was no significant difference between the neighboring plants and the control plants. The contents of tannin and total phenol in the oviposited plants of P.×euramericana.‘Bellotto' was significantly higher than that in the control plants, and the content of tannin in the neighboring plants was significantly higher than that of the control plants.[Conclusion] The content of nutrients in the oviposited and neighboring plants of the two clones changed and the content of secondary metabolites increased at different degrees.Therefore, both the oviposited and neighboring plants of the two clones can produce certain induced insect resistance after oviposition of M.sieversi.
